HOSE CLAMP Filed Aug. 29, 1941 INVENTOR ATTORNEY Patented Mar. 31, 1942UNITED STATES PATENT OFFICE Harold Gass, New York, N. Y.

Application August 29, 1941, Serial No. 408, 24 I 3 Claims. (on. 24-19)Fig. 2 is a sectional view'on the line 2-2 of Fig. 1, and

l Fig. 3 is a perspective view of the clamping bracket.

According to the invention, the hose clamp l comprises a relatively thinmetal strap ll preferably of non-resilient but deformable and flexiblestock. This strap is substantially annular and includes an inner arcuateend l2 provided with reinforcing ribs l3.

Supporting means in the form of a lug gen-' erally designated i4 isbentfrom the body of the strap providing a plurality of closely positionedwalls I! having horizontally alined perforations it for the reception ofthe unthreaded portion of th threaded shank ll of a bolt which embodiesa slotted head H.

The other end to of the strap is provided with spaced perforations isselectively and removably receiving the free end of the threaded portion2a of shank i'l, the latter being also received in the threaded opening2i of the upstanding wall or leg 22 of the bracket broadly denoted 23.

This bracket has a downwardly and outwardly against the outer end of thestrap as shown.

In instances where it is desired to remove the clamping relation, thebolt is acfiustably rotated until it leaves the, receiving opening I!after which the outer end l8 of the strap may be desirably adjusted topermit the strap to accommodate another size of pipe.

Various changes may be made in details of construction and arrangementof parts without departing from the spirit of the invention orsacrificing any of the advantages thereof inherent therein.

I claim:

1. In a hose clamp, an annular strap including perforated supportingmeans, said strap having an inner end and an outer end movable towardsor away from each other, said outer end including a plurality of spacedopenings, a threaded bolt removably sustained by said supporting means,and abracket having an upper upstanding legand a lower leg inclineddownwardly and inclined leg 24 provided with the transversely arrangedopening 25 adapted to receive end l8 of the strap as illustrated.

With the bolt inserted in lug I4 and in the upstanding wall 22 andthreaded in one of the openings Is, the bore of the latter preventsslackening of the strap even though the latter is encompassing a pipeline or the like not illustrated.

However the inner and outer ends I2 and it of the strap may be adjustedtowards or away from each other depending upon the rotation of the bolt.Thus the strap may be desirably and adjustably held in a. clampingrelation about a pipe it encompasses. If in aclamping relation, the apexor corner 28 defined by the inclined face 21 of opening or gap 25 andthe lower or outer.

face 28 of the lower inclined leg 2! constitute means for urging theportion 29 of the outer end ll towards the inner end I2 of the strap,hence precluding longitudinal slippage between the inner and outer endsof the strap. More specifically, the superimposed portions 30 and 3! ofthe outwardly in respect to said upstanding leg, the latter having meansto adjustably receive the threaded shank of said bolt whereby the latterenters one of said openings to prevent slackening of said strap,saidlower leg including a gap for receiving said outer nd and having acorner portion bounding said gap, said corner portion on rotation ofsaid shank in one direction cooperating with said outer end to urge thelatter tightly towards said inner end to prevent longitudinal slippageof said ends in opposite directions.

'2. In a hose clamp, an annular strap including upstanding perforatedsupporting means, said strap having an inner end and an outer end mov-40 able towards or away from each other, said outer end including aplurality of spaced openings, a threaded bolt removably sustained bysaid supporting means above said ends, and a removable bracket havinganupper upstanding leg and a lower leg inclined downwardly and outwardlyin respect to said upstanding leg, the latter having means to receivethe threaded shank of said bolt whereby the latter enters one of saidopenings to prevent slackening of said strap, said lower leg including agap for removably receiving said out er. end and having a lower comerportion bounding said gap, said corner portion on rotation of said shankin one direction cooperating with said inner and outer ends I. and 19are held in an outer end to urge the latter tightly towards and againstsaid inner end to prevent longitudinal slippage of said ends in oppositedirec..'.ons.

3. In a hose clamp, an annular strap including perforated supportingmeans, saidstraphavingan inner end and an outer end movable towards oraway from each other, said outer end including a plurality of spacedopenings, a threaded bolt removably sustained by said supporting meansabove said ends, and a bracket having an upper upstanding leg and alower leg inclined downwardly and outwardly in respect to saidupstanding leg, the latter having a threaded opening to 10 receive thethreaded shank of said bolt whereby the latter enters one of saidopenings 01 said outer end to prevent slackening of said strap, saidlower leg including a gap having an inclined i'ace constituting' onewall of said gap, said lower leg having a bottom face disposeddownwardly and outwardly relative to said inclined face and definingtherewith a corner portion in part bounding said gap longitudinallythereof, said comer portion only of said lower inclined leg on rotation01' said shank in one direction cooperating with said outer end to urgethe latter tightly towards and against said inner end to preventlongitudinal slippage of said ends in opposite directions.
